Applicable minerals: Lithium ores have industrial value, especially lithium ores in fine-grained disseminated form.

Main process: Common lithium ore flotation methods include forward and reverse flotation.

Positive flotation method: After the lithium ore is finely ground (avoid over-grinding that may cause mud formation), add a strong alkali for flotation. Add oleic acid after high concentration, strong stirring, and multiple scrubbings to desludging the lithium ore in an alkaline medium. Its soap salts are used as collectors to directly float out the lithium concentrate, leaving gangue minerals in the tank. This process does not require the addition of inhibitors.

Reverse flotation method: With the help of the alkaline environment created by lime, starch, dextrin, and other substances are added to inhibit the floating of lithium ore, and at the same time, a cationic collector is used to float the silicate gangue minerals to the surface of the slurry. The product is lithium concentrate. If lithium ore contains iron minerals, a foaming agent (such as HF or resinate) can be added to help further remove iron minerals and other impurities.400TPD Lithium Ore Processing Plant.
